Hi,
Flavio, if you can, please try commenting out a line in fs/aufs/file.c
and reproducing the problem.
const struct address_space_operations aufs_aop = {
:::
- .migratepage = aufs_migratepage,
+ /* .migratepage = aufs_migratepage, */
:::
};
If opensuse have a package called numaclt and it contains a command
named migratepage, then it may be a easier way to reproduce (I am not
sure).
Current my questions are
- is this problem NUMA machine specific?
- is your machine NUMA avaliable? in other words, does your machine have
multiple memory node?
